For some people, frequent feeding works. For others, it doesn't. It all comes down to personal preferrence.

Just for educational purposes, eating more frequently will do nothing to "boost" or "slow" your metabolism. And metabolic function does not change as easily as many are mislead to believe.

It has been suggested for people that are prone to overeat that it is better for them NOT to eat as frequently as 6 meals because that then reinforces the problem. So, for some, there are good reasons to stick to less meals as long as they can get the required nutrients in.
